Directions for Use

For control of annual and perennial broadleaf weeds including invasive and noxious weeds, certain annual grasses, and certain woody and vines, that are near and up to the water’s edge.

Environmental Hazards Do not apply directly to water. Take care to minimize the incidental overspray along the shoreline when applying to terrestrial plants at the water’s edge or to water in areas where surface water is present. Do not apply directly to intertidal areas below the mean high water mark, except as permitted on this label. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. Do not contaminate water when disposing of equipment wash water or rinsate.

Use Information

Control of Terrestrial Weeds that are near and up to the Water’s Edge

Milestone can be used to treat terrestrial weeds that extend up to the water’s edge. Do not apply directly to water. This product must not be used to treat vegetation standing in the water. When controlling terrestrial weed species near and up to the water’s edge, take precautions to minimize incidental overspray to the adjacent water. Consult local public water control authorities before applying this product near public waters. Permits may be required to treat such areas. Apply the specified rate, listed in the table below, as a coarse low-pressure spray as ground broadcast or spot applications. Do not apply aerially for control of weeds growing at or near the water's edge. Spray volume should be

Page 1 of 5 sufficient to uniformly cover foliage. Increase the spray volume to ensure thorough and uniform coverage when target vegetation is tall and/or dense. It is also permissible to treat target weeds within dry non- irrigation ditches and seasonally dry transitional areas between upland and lowland sites (such as flood plains, deltas, marshes, prairie potholes or vernal pools), but only at times when those sites are dry and are forecasted or managed by water control systems to remain dry for at least 2 weeks following application.

Use Rate Restrictions: Do not broadcast apply more than 7 fl oz per acre of Milestone per year. The total amount of Milestone applied broadcast, as a re-treatment, and/or spot treatment cannot exceed 7 fl oz per acre per year. Spot treatments may be applied at an equivalent broadcast rate of up to 0.22 lb acid equivalent (14 fl oz of Milestone) per acre per year; however, not more than 50% of an acre may be treated at that rate. Do not apply more than a total of 0.11 lb acid equivalent (7 fl oz) per acre of Milestone per year as a result of broadcast, spot or repeat applications.

Weeds and Woody Plants Controlled Note: Numbers in parentheses (-) refer to specific use directions for a particular weeds species.

(1) Sulfur cinquefoil or oxeye daisy: Apply Milestone at 4 to 6 fl oz per acre to plants in the prebud stage of development. (2) Orange or yellow hawkweeds: Apply Milestone at 4 to 7 fl oz per acre to plants in the bolting stage of development. (3) Diffuse, spotted, and squarrose knapweeds: Apply Milestone at 5 to 7 fl oz per acre when plants are actively growing with the optimum time of application occurring from rosette to the bolting stages of development or in the fall. Plants will be controlled by mid-summer and fall applications even though plants may not show any changes in form or stature the year of application. (4) Russian knapweed: Apply Milestone at 5 to 7 fl oz per acre to plants in the spring and summer at early bud to flowering stages and to dormant plants in the fall. (5) Mullein: Apply to the rosette stage (6) Tropical soda apple: Apply Milestone at 5 to 7 fl oz per acre at any growth stage, but application by flowering will reduce seed production potential. (7) Malta, purple, and yellow starthistle: Apply Milestone at 3 to 5 fl oz per acre to plants at the rosette through bolting growth stages. (8) Bull, musk, and plumeless thistles: Apply Milestone at 3 to 5 fl oz per acre in the spring and early summer to rosette or bolting plants or in the fall to seedlings and rosettes. Apply at 4 to 5 fl oz when plants are at the late bolt through early flowering growth stages. 2,4-D at 1 lb ae/acre should be tank-mixed with Milestone starting at the late bud stages

Page 4 of 5 (9) Canada thistle: Apply Milestone at 5 to 7 fl oz per acre in the spring after all plants have fully emerged (some may be budding) until the oldest plants are in full flower stage. Use the higher rate when applying to the flower stage. Applications are also effective in the fall before a killing frost. Use higher rates for older/dense stands or for longer residual control. (10) Absinth wormwood: Apply 6 to 7 fl oz per acre before wormwood is 12 inches tall. When applying by air on CRP, coverage is important and a minimum of 3 GPA is specified. Remove old duff and litter by fire or mowing for best results (11) Invasive knotweeds: Japanese, Bohemian, giant knotweeds: Optimum suppression of invasive knotweeds with Milestone herbicide is obtained when applications are made to plants that are at least 3 to 4 feet tall. Results of field trials conducted in the western U.S. indicate that high volume applications (100 gpa or greater) of Milestone at 7 fl oz/A or a spot treatment rate up to 14 fl oz/A applied in summer will provide good control of invasive knotweeds. In the upper Midwest, mowing in summer followed by fall application of Milestone (prior to frost) provided the best control. Infestations of invasive knotweed that are mowed should be allowed to regrow to at least 3 feet in height prior to herbicide treatment. Monitoring and follow-up herbicide treatments on regrowth will be necessary to control resprouts and achieve long-term control. (12) Purple loosestrife: For optimum control apply Milestone at 7 fl oz per acre plus 1 pt to 1 qt of 2,4-D amine or 1 to 2 qts of Garlon 3A. Spot treatments may also be made by applying Milestone at 14 fl oz (see Spot treatment section of the label) with or without the addition of 2,4-D or Garlon 3A. (13) Fiddleneck: For optimum control apply Milestone at 4 to 7 fl oz per acre when the plants are young and before flowering. Use higher rates if the plants are older and larger. In optimal application timing is November through March.
